Detectives want to speak to them about an alleged sexual assault on four 13-year-old school boys in Hackney.

They have released the previously unseen CCTV stills and footage after four boys were reportedly groped on a footpath as they walked to school at around 8am on Wednesday July 8 last year.

CCTV shows two men laughing and joking in a shop near the alleged London crime scene:

The boys said they were approached by two men – but managed to escape and tell their school what happened.

The same men are believed to have assaulted two school girls close to where this happened, in a separate attack.

Police are appealing for anyone with information to come forward.
